The invention relates to the field of motor control, and discloses a rotating speed loop control method and device during series power generation and a medium, and the rotating speed loop control method comprises the steps: sampling a target torque given value of an engine according to a set sampling period; the rotating speed loop controller calculates the difference between the target torque given value at the current moment and the target torque given value at the previous moment to obtain the target torque variable quantity of the engine; according to the rotating speed difference between the target rotating speed and the actual rotating speed of the generator, a proportional output item and an integral output item are obtained through calculation; and obtaining an actual output torque value according to the proportional output item, the integral output item and the target torque variation, and controlling the actual rotating speed of the generator at least according to the actual output torque value. According to the rotating speed loop control method and device and the medium, the problems that according to a traditional rotating speed loop control method, rotating speed overshoot occurs when the needed generated power changes, and the rotating speed adjusting efficiency is low are solved.
